How to choose a laser marking machine, then you need to master these points!

The laser marking machine irradiates the workpiece with a high-density laser beam. The surface of the workpiece absorbs laser energy, which causes the surface of the material to undergo deformation, melting, ablation, and evaporation, thereby forming a safe mark. Today's laser marking machines have been widely used in various industries, playing the role of anti-counterfeiting traceability, exquisite beauty and so on.

At present, laser marking machines are divided into semiconductor laser marking machines, CO2 laser marking machines, and fiber laser marking machines according to laser sources. They have different marking effects for different materials. Generally speaking, semiconductor and fiber laser marking machines are suitable for marking metals, plastics and other materials. CO2 lasers are mainly for non-metallic materials, such as acrylic, transparent plastic, ceramics, and glass.

So how to choose a suitable laser marking machine? Then you need to master these points!

Laser source for marking machine. It depends on the material of the workpiece you want to process. For hardware, plastic, label paper and other materials, use a longer-wavelength fiber laser marking machine; bamboo, cloth, ceramics, acrylic, * and other materials use a shorter-wavelength CO2 laser. Marking machine: If it is heat sensitive materials such as films, fruits, eggs, cartons, strengthened glass, etc., use a UV laser marking machine with a moderate wavelength.

Of course, it is not said that one material is only suitable for one laser source, and multiple laser sources can be used for the same material. It depends on the fineness of your processing requirements.

Marking machine power. Laser power is sometimes the key to determining the speed and effect. Generally speaking, like UV engraving paper, film, plastic, you can use low power 1.2W to mark, but engraving glass requires UV 3W or even 5W power to engrave. It works; like hardware, 20W optical fiber can be used, but if you pursue high efficiency and high speed, you need 30W or higher power to achieve it.

The main hardware structure of the marking machine. The main hardware structure of the laser marking machine, including the laser, laser scanning galvanometer, focusing system, laser power supply and calculation notification system, you only need to choose whether to import or domestic according to your processing needs, especially for accuracy. If there are high requirements, please make it clear with the manufacturer.

There is also a computer notification system and there is a computer notification system. There are many kinds of software used on laser marking machines. Some are conventional, some are developed by themselves, or the conventional software is re-developed, and you decide which software to use. It is necessary to figure out whether there will be a need for secondary development.

Marking machine price. In fact, the price is changed according to the customer's demand configuration, so here is just a rough reference price, the price of general fiber laser marking machine (20W-50W) ranges from 20,000 to 80,000; carbon dioxide laser marking The price of the machine (10W-100W) ranges from 30,000 to 180,000; the price of the UV laser marking machine (1.2W-10W) ranges from 60,000 to 260,000.

In addition, when using laser equipment, the accuracy, engraving effect, speed, and automation, customized fixtures and other requirements must be proposed to the manufacturer in advance, and confirmed during the sample test and plan, so as to avoid purchasing those that do not meet the user's requirements. Marking machine affects user experience. What is considered is the life, stability, portability and after-sales service of the marking machine. Like longevity and stability, it depends on the heat dissipation and whether the brand is big enough; portability depends on the appearance and model of the product.
